Modifications can be raised by any party to the UNC and should be made on the standard forms available at www.gasgovernance.co.uk/unc/templates. Modifications should be sent to firstname.lastname@example.org.
Each modification is given a unique number. Suffixes are added to highlight the status of some modifications. These are:
A - Alternative (followed by B, C etc if more than one Alternative is raised)
S - Self Governance
V - Varied
Multiple suffixes can also apply, for example when an Alternative is Varied, this will be numbered xxxxAV
Modifications can be amended prior to being issued to consultation and the number is not changed. Any subsequent amendment requires a Variation Request to be raised and considered by the Modification Panel, and this becomes a Varied Modification with the V suffix.
